An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-37903 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- vm2 (npm): affected all versions up to 3.9.19; no fix listed\n- vm2 (npm): affected all versions up to 3.9.19; no fix listed\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2023-37903/ (Markdown: https://insights.sbomify.com/CVE-2023-37903/index.md)","id":"CVE-2023-37903","markdown":"https://insights.sbomify.com/CVE-2023-37903/index.md","name":"CVE-2023-37903","record":{"aliases":["GHSA-g644-9gfx-q4q4","ROOT-APP-NPM-CVE-2023-37903"],"analysis":{"component_type":"library","fix_type":"end_of_life","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js sandbox library","requires_auth":"none","summary":"Attackers can escape the vm2 sandbox and execute arbitrary code via Node.js custom inspect functions, requiring users to migrate to alternative solutions.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"vm2","vendor":"vm2_project"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"vm2 is an open source vm/sandbox for Node.js.
